How much H2O is produced when 40000 g of
C2H, burns completely?
Answer in units of g.

Answers

Answer 1

Answer:

1200g H20.

Explanation:

Write out the balanced equation... when an organic compound is burned, like C2H2, it is burned in oxygen (O2) and produces Water and Carbon Dioxide (CO2)

so 2C2H2 + 5O2  =  2H2O  + 4CO2

now that you have a balanced equation just convert to moles and solve

2000g C2H2 * 1mol C2H2 / 30gC2H2 * 2mol H2O/2mol C2H2 * 18gH2O/1molH20 = 1200g H20.

can someone explain in detail how molar mass, Avogadro's number, and volume are all connected through moles? Im so confused :(

Answers

Answer:

See Explanation

Explanation:

By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...

1 mole of hydrogen atoms (H) = 1.00794 grams

1 mole of molecular hydrogen (H₂) =  2.01588 grams

1 mole of any substance = 1 formula weight in grams

1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams

In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.

For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions  are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...

Given   N₂(g) + 3H₂(g) => 2NH₃(g)  is assumed to be at 0°C; 1 Atm pressure.

Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)

Molecular Hydrogen = 3 molar volumes = 3 x  22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)

Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃

What do u mean by electronic configuration? What are basic requirements while writing electronic configuration of an element (atom) ?

Answers

Yes that is right I look it up thanks for the points

The basic requirement while writing the electronic configuration of an element (atom) is its atomic number.

Explanation:

The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.It only requires an atomic number of an element to write its electronic configuration.The atomic number is equal to the number of protons in an atom and that is equal to the number of electrons.And the filling of electrons is done according to the Aufbau principle, the electrons will be first filled in the atomic orbitals with lower orbital energy before filling the atomic orbital with higher energy.The sequence of the atomic orbitals from lower energy to higher energy is:

    [tex]1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d...[/tex]

For example:

  The atomic number of gallium is 31, its electronic configuration will be:

   [tex][Ga]=1s^2 2s^2 2p^63s^2 3p^6 4s^2 3d^{10} 4p^1[/tex]

Answer:

Explanation:

H .  +  H .   ----->  H:H            {":" represents a covalent bond, that is, a shared pair of electrons}

A Lewis structure is a convention used to represent the covalent bonding in a molecule.   Dots or lines are used to represent

valence electrons (electrons available for bonding).  The Lewis structure for the hydrogen molecule is as follows.

     H:H  or  H-H

A bonding pair is an electron pair shared between two atoms.

A nonbonding pair (lone pair, unshared pair) is a pair of electrons that remains on one atom and is not shared.

Visit: gotit-pro.com

Explanation:

1) Convert pressure to atm
119 kPa x 1 atm/101 kPa = 1.18 atm

2) Convert temperature to Kelvin
35 + 273 = 308 K

3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)

V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)

V = 2.08 L

It was the worst fight of their marriage. For Mrs. Song, it was not merely that her husband had been disrespectful of the government; for the first time in her life, she felt the stirrings of fear. Her conduct had always been so impeccable and her devotion so genuine that it never occurred to her that she might be vulnerable. 9. Why did you say such nonsense when there were neighbors in the apartment? Didnt you realize you could have jeopardized everything we have? she railed at him. 10. In fact, they both realized how lucky they were. If not for Chang-bos excellent class background and his party membership, he would not have been let off so lightly. It helped, too, that Mrs. Song had at various times been head of the inminban in the building and commanded some respect from the state security officers.
